I NVENTOR,

GIACOMO M. BOA/ALI)! Zaermo CROSS REFERENCE TO RELATED APPLICATION This application is a continuation-in-part of my copending application Ser. No. 89,576, filed Nov. 16, 1970, now abandoned.

BACKGROUND OF INVENTION This invention relates to a novel ventilating device which is especially adapted for use in combination with a conventional, commercial garment pressing machine for providing ventilation to the area surrounding the machine. More specifically, it is an improvement upon the ventilating devices described in my U.S. Pat. No. 3,523,381, issued Aug. 11, 1970.

As described in U.S. Pat. No. 3,523,381, garment pressing machine operators have normally been subjected to the great quantities of heat and steam generated by the machines causing poor working conditions and sometimes physical impairment of the operator. The invention of said patent substantially solved these problems by providing a ventilating device as an integral part of the pressing machine or as a portable attachment to it. The device consisted of an air blower positioned at or near the base of the garment pressing machine, an elongated vertical tube, the lower end of which is attached to the blower exhaust and a nozzle attached to the upper end of the tube for directing a stream of air exiting from said upper end in a generally horizontal direction at about the operators head level across the garment pressing machine.

DESCRIPTION OF INVENTION This invention concerns a ventilating device especially adapted for use with garment pressing machines which generates a stream of air which is deflected substantially horizontally in all directions in the horizontal, thereby providing significantly better ventilation than was afforded by the devices of U.S. Pat. No. 3,523,381.

This novel ventilating device basically comprises a forced air generating means positioned near a source of cool air, a generally vertically-extending conduit, one

end of which communicates with the exhaust of the air generating means and the other end of which is open to the atmosphere for carrying the stream of cool exhaust air from the air generating means upwardly and a deflector positioned at a predetermined height above the open end of the conduit for deflecting the stream of air generally horizontally in all directions in a horizontal plane directly below the deflector.

It is therefore a primary object of this invention to provide a novel ventilating device which distributes a stream of air in all directions in a horizontal plane of predetermined height.

Another object of this invention is to provide an improved ventilating device for use in combination with a garment pressing machine either as in integral'part thereof or as a portable device positioned adjacent thereto which substantially improves operator comfort, safety and efficiency.

Other objects and advantages of this invention will be apparent from the following detailed description of the invention.

DESCRIPTION OF DRAWINGS FIG. 1 is a perspective view illustrating a portable embodiment of the air ventilating apparatus of this invention positioned adjacent a conventional, commercial garment pressing machine.

FIG. 2 is a front view of the air ventilator of FIG. 1 in partial secton along line 22 of FIG. 1.

Referring to FIG. 1, a ventilator, generally designated 10, embodying my invention is positioned adjacent a conventional garment pressing machine, generally designated 1 1. The garment pressing machine 11 has a base support 12 for supporting the remainder of the machine and for housing the usual pressing level means and vacuum lines controlling the operation of the machine in response to foot pressure by the operator. A table 13 is supported on base 12. In turn table 13 supports a buck stand 14 and a buck 15 which is the stationary,-lower pressing element of the machine. A head 16 serves as the upper pressing element and is mounted on a pressing level 17.

As shown in FIGS. 1 and 2, ventilator 10 has a generally rectangular housing 18 which houses a driven air blower, generally designated 19, which includes an impeller 20 positioned in a circular aperture 21 in wall 22 of housing 18. Impeller 20 is attached to the driven sprocket of an electrical motor 23. The housing 18 sits on the floor adjacent the garment pressing machine 11 and the impeller 20 sucks in the relatively cool air from approximately floor level into the interior of housing 18. The circular top 27 of housing 18 substantially overhangs the sidewalls of the housing to protect the impeller intake from falling garments and dust.

An elongated conduit 28 extends through top 27 with its lower end 29 opening into the interior of housing 18. While conduit 28 is illustrated as being generally rectangular, it may be of any desired shape, Conduit 28 extends vertically upwardly from top 27 and carries the exhaust air from impeller 20 upwardly toward upper end 30 of conduit 28. The air (illustrated by wavy arrows in the drawings) exits from upper end 30 as a substantially upwardly directed stream of air.

The air stream exiting from upper end 30 flows upwardly in the open space between end 30 and a disc shaped deflector 31. When it reaches the underside of deflector 31 it is deflected thereby outwardly from the center line of the air stream in all directions in a horizontal plane directly beneath the underside of deflector 31 thereby providing multi-directional ventilation.

Deflector 31 is mounted at a'predetermined height on a rod 33, preferably approximately level with the head of the garment pressing machine operator. The lower end of rod 33 is threaded and extends horizontally through wall 22 of housing 18 and is bolted thereto. The lower horizontal portion 34 of rod 33 extends inwardly into the interior of housing 18 from its connection at wall 22 to a point directly below the center of conduit 28. At that point, horizontal portion 33 is connected to a vertical portion 35 by an elbow 36. The vertical portion 35 extends upwardly through the center of conduit 28 and extends upwardly from upper end 30 for a substantial distance thereabove.

A collar or sleeve 40 having a central bore 41 is mounted about vertical portion 35 of rod 33. A set screw 42 extends horizontally through collar 40 for fixing the collars position on portion 35. The vertical position of the collar'on portion 35 may be adjusted by loosening set screw 42, sliding collar 40 upwardly or downwardly on portion 35 and tightening set screw 42.

Deflector 31 has a hole 43 in its center of smaller area than the area of the top side of collar 40. When deflector 31 is mounted on rod 33 above collar 40, deflector 31 rests onvthe top of collar 40. Thus, the height of deflector 31 may be adjusted by adjusting the vertical position of collar 40 as described above.

Obvious variations of the above described embodiment will be readily apparent to those skilled in the art. For instance, cooling means such as refrigerating coil or heating means such as. a heating coil may be included in the ventilating device along with thermostat controls to regulate the temperature of the air stream issuing from the ventilator conduit. It is intended that such modifications as well as others that are readily apparent to those skilled in the art be included within the scope of the following claims:
